Interactive display techniques: examples from NMR phase velocity mapping and inflow angiography

The author presents an intuitive, graphic-style human-computer interface that has been designed and implemented in response to the growing need for processing capability in medical imaging and the increase in readily available computer hardware to provide it. The design makes use of metaphor to provide consistency in the interfaced and order to internal data structures. The result is an interactive tool that is used effectively to color-code phase-velocity-mapped imaged and isolate and render 3-D inflow angiography data in nuclear magnetic resonance (NMR) imaging
